MASSACHU- WIRE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 447,999, dated March 10, 1891.

Application filed September 17,1890. Serial No. 365, 307. (No model.)

To aZZ whom it Hwy concern:

Be it known that I, OLIVER ARNOLD, a citizen of the United States, residing at Leicester, in the county of IVorcester and State of Massachusetts, have invented a new and useful Improvement in W'ire Cutters, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The object of mypresent invention is to afford a wire-cutting instrument having jaws of semi-cylindrical form that shear against each other by oscillating action, as more fully hereinafter explained.

In the drawings, Figure l is a perspective view of my improved wire-cutter as adapted for a hand-tool. Fig. 2 is a side view of the same. Fig. 3 shows the two parts separated. Fig. 4 is a top view of the wire-cutting jaws. Fig. 5 is a horizontal section at line 00 as, showing the outer cylindrical jaw separate. Fig. 6 is a horizontal sect-ion at line a: 0:, showing the inner cylindrical jaw. Figs. 7 and 8 illustrate the adaptation of my invention as a wire-cutter for machinery.

My improved wire-cutter consists, essentially, of two cylindrical parts, one of which is adapted to fitinto and oscillate within the other, the end or ends of these cylindrical parts being cut away at one side, so as to form semi-cylindrical jaws with cutting-edges that stand opposite to each other, and which shear past each other at their cutting-edges by oscillating movementof the cylinders for severing a wire passed between the jaws in a direction transverse to the axis of the cylin ders.

In referring to parts on the drawings, A indicates the outer cylinder, a part of which is cutaway to form a jaw or cutting-edge, as at a, and B denotes the inner cylinder, a part of which is cut away on the side opposite to that of cylinder A, so as to form a jaw or cutting-edge, as at b. The cylinder'B fits within the cylinderA, and is made of substantially the same length. A lever 'or handle A is rigidly attached to the part A, and a handle B is properly fitted to pass through an opening 0 in the side of the cylinder A, and is connected with the cylinder B. A pin, screw, or stud D is arranged through the axis or center thereof to hold the parts together. A spring F is preferably attached to one of the handles to press against the other to forcetheln apartand open the jaws. The jaws and cut-away parts of the cylinders are so disposed in relation to each other that when the handles are spread apart a space, as at e, is open between the cutting-edges a and I), through which the wire to be severed is passed, and when the handles are pressed together the cylinders are oscillated in relation to each other, closing the space between the jaws and causing the cutting-edges to shear past each other in a manner to sever the wire by an easy and powerful action.

The parts A and l3,with theirhandles, can be made of any size and strength for cutting wires or rods of any particular dimension; but I. prefer to make the tool of such proportion that the opening of the jaws will not admit the entrance between them of a wire of larger gage than can be readily severed by the tool in any given size or proportional strength of cutting-jaws.

In Figs. 7 and 8 I have illustrated an adaptation of my improved cutter for machine work, as for cutting wire in card-setting niachines, or for other like purposes. In this the cylinders A and B, having the cut-away ends and cutting-edges a and b, are supported upon a pin or stud G, which is fixed stationary in the frame II. The inner cylinder B is made fast to the stud by a set-screw I or other convenient means, and the outer cylinder A is oscillatively mounted thereon and provided with a lever A by which it is worked for opening and closing the cutting-jaws. Said lever can be clamped to the outer surface of the cylinder A by the screw .I in the manner illustrated. A hole 9, formed laterally through the end of the stud G, serves as a guide for the wire IV as it is fed forward. Any suitable means can be employed, as a lever, for imparting movement to either or both the cylindrical parts to open and close the jaws.

If the cutter-jaws become dull and worn, their ends can be ground off and the two cyl- IOC inders setforward by means of the adjustingscrew 'm, so that a new portion of the edge is brought into position for severing the wire.

The construction shown and described atfords a very convenient and effieient form of wire-cutting mechanism.

I claim as my invention herein to be se cured by Letters Patent- 1. A Wire-cutter consisting of two cylindrical parts, one arranged within the other, portions of said cylinders being cut away to form semi-cylindrical jaws with cutting-edges that shear past each other by rotative action of one cylinder in relation to the other, and an operating leveror levers for imparting oscillating movement to one orboth of said cylinders, substantially as set forth.
